With the classic narcissist, language is used cruelly and ruthlessly to ensnare one's enemies, to saw confusion and panic, to move others to emulate the narcissist ("projective identification"), to leave the listeners in doubt, in hesitation, in paralysis, to gain control, or to punish. Language is enslaved and forced to lie. The language is appropriated and expropriated. It is considered to be a weapon, an asset, a piece of lethal property, a traitorous mistress to be gang raped into submission.
With cerebral narcissists, language is a lover. The infatuation with its very sound leads to a pyrotechnic type of speech which sacrifices its meaning to its music. Its speakers pay more attention to the composition than to the content. They are swept by it, intoxicated by its perfection, inebriated by the spiralling complexity of its forms. Here, language is an inflammatory process. It attacks the very tissues of the narcissist's relationships with artistic fierceness. It invades the healthy cells of reason and logic, of cool headed argumentation and level headed debate.
